蓝牙广播 [英] Bluetooth broadcasting

问题描述

我想从使用蓝牙众多附近的设备一个设备广播数据。现在，我知道蓝牙广播存在，但使用Android的现有的API这可能吗？如果没有，是否有任何其他第三方提供的API在那里，它们能够呢？

I want to broadcast data from one device using Bluetooth to numerous nearby devices. Now, I know Bluetooth broadcasting exists, but is it possible using Android's existing API? If not, are there any other 3rd party APIs available out there which are capable of it?

有关蓝牙广播另一个问题：
你就可以开始听一个持续的广播并接收数据，即使你不听，因为广播已经开始？例如，让设备A是该广播，并且他超过5秒的过程中广播以下数据：

Another question regarding Bluetooth broadcasting: Can you start listening to an ongoing broadcast and receive data from it, even if you weren't listening since the broadcast has started? For example, let device A be the broadcaster, and he broadcasts the following data over the course of 5 seconds:

1 2 3 4 5 6 7 8 9 10

设备B在整个广播接收到的数据，他因此获得：

Device B received data throughout the entire broadcast, so he received:

1 2 3 4 5 6 7 8 9 10

器件C接收到开始听只有2秒后，当设备A正在播放 5 。他将获得其余的（ 5 6 7 8 9 10 ）如预期？

Device C received started listening only after 2 seconds, while device A was broadcasting 5. Will he receive the rest (5 6 7 8 9 10) as expected?

推荐答案

由于数据包没有蓝牙广播期间承认，对于以后出现，广播从节点（接收器）之间的主（发送方）没有区别并在那里从一开始，并没有收到任何报文从节点

As packets are not acknowledged during a Bluetooth broadcast, there is no distinction for the master (sender) between a slave node (receiver) that appears later in a broadcast and a slave node that was there from the beginning and didn't receive any packet.

所以，是的，装置C将从5如果蓝牙连接所有一般条件都满足，接收数据的新包了起来。

So, yes, the Device C will receive the new packets of data from 5 and up if all general conditions for a bluetooth link are met.
